What processes can be used for large box type resistance furnaces?

Large box type resistance furnaces can complete various processes in the metal industry, as follows:

Metal heat treatment process
Annealing: Heating the metal to a certain temperature and keeping it warm to release internal stress and optimize its structure. For example, post weld heat treatment of P92 steel can reduce residual stress in welded joints, improve microstructure, reduce hardness, and enhance toughness. The temperature control system of a large box type resistance furnace can stably control the temperature during annealing, ensuring the stability of the metal.
Quenching: Quickly cooling the heated metal to obtain hardness and strength. A large box type resistance furnace can quickly heat up to the required quenching temperature, and the atmosphere inside the furnace is controllable, which can avoid oxidation of the metal surface.
Tempering: As an important process for restoring toughness after quenching, the uniform heating characteristics of large box type resistance furnaces ensure the consistency of tempering temperature and effectively improve the comprehensive performance of metals.

Metal melting process
Small batch, high-precision metal alloy production: The heating process of the large box type resistance furnace is fast and controllable, which can achieve precise temperature adjustment according to the melting process requirements of different metals, meeting the needs of small batch, high-precision metal alloy production.
Meeting the melting needs of different metals: Different types of metals, such as aluminum, copper, stainless steel, etc., have different temperature and atmosphere requirements during the melting process. A large box type resistance furnace can achieve optimal melting conditions for each metal through its multi-stage temperature control system, providing high-quality metal materials for subsequent casting and forming.

Research and development process of metal materials
Characteristic analysis and performance testing: In laboratory environments, researchers often need to conduct characteristic analysis and performance testing on new metal materials. Large box type resistance furnaces are suitable for high-precision experiments due to their small temperature fluctuations, making them particularly suitable for observing and analyzing phenomena such as phase transition and diffusion of metal materials at different temperatures.
Atmosphere melting and reaction: Large box type resistance furnaces can be combined with gas control systems for atmosphere melting and reaction, providing an important experimental platform for the development of new materials.
